Awww yeahhh! DOS! I remember making a huge batch file menu to navigate my system using CHOICE.COM and ERRORLEVELs as conditionals. It was great.
If you want to try Linux, you can always try booting a LiveCD of some sort, what that means is that you can boot the CD into the OS without actually installing it. It's pretty nifty. Here is a decent Linux Distro that allows you to do this. (Linux Mint)
Another option is to use software like VMWare Player (Free) to let you use he system in a virtual machine, which is pretty much a program that acts like another computer that you can work with... It's also pretty nifty.
One thing about Linux though, it is not really for everyone, while I rather it, others will still like other things, and that is OK, to each their own, so don't be afraid to try it and say "IT ROCKS!" or "IT SUCKS!". :P
